TO LL WHOM IT MAY' 00N CERN i Be it known that I, DANIEL P'. LCEY, of Orfordville, in the county of Rock, and State of Wisconsin, have invented a new and useful Improvement in Sash-Supporters and Locks; and I do hereby declare that the following is a suilicently full, clear, and exact description thereof to cnable'one skilled in the art to which my said invention appertains to make and carry it into effect, reference being `had to theaccompanying drawing, which is` made a part of this specification. t

My present invention 'is intended as an improvement on thesash-supporter for which Letters Patent, No. 57,733, were, on the fourth dayof September, 1866, granted to Lacey and Bartlett i t My improvement consists in the enlargement or widening of the end of the bolt or dog, for the purpose of increasingits bearing-surface, and in the provision of a' suitable notch or recess in the face of the lock, for the' reception of said enlarged portion when the bolt is retracted.

Figure 1 represent-s an elevation of a' sash-supporter having my improvement applied in position in the window-jamb, a portion of which is shown in section, the side of said supporter nearest the spectator being removed, to expose its internal construction.

' Figure 2 is a front view of the supporter, detached.

The sash-supporter represented isanalogous to that patented by Lacey and Bartlett, and before referred to,

and is intended to bc inserted in the jamb of the window at any suitable point, and operateby engaging with A suitable holes or indentations in the edge of the sash, or by friction at intermediate points.

The casing, A, is preferablycast in one piece, except the removable side A1, which is attached thereto inl theusual manner, by a screw. engaging with the female. screw' in theboss a.

B` C are the bolts, and E E spiral springs, by which said bolts are held in their protruded position, a a being ilanges or partitions cast on the casingA, to ferm sockets for said springs. i

The bolt B is retracted by means ofan angular key insertedin a corresponding aperture, b, in its hub, and in its movementretracts the bolt ,C by its projection I1 coming in contact with the downward projection cof said bolt..

The face or point B of the bolt B is laterally enlarged-or widened to any desired extentto increase its bearing-surface, an'd the face oi' the casing A is notched or recessed, as at A, for the reception of said enlarged projection when the bolt is retracted. r I am thus enabled to construct the bolts with as broad. faces as may be required for the purpose for which they are employed, without enlarging the lock proper,l oir-increasing the cost of manufacture.

- In'using my invention in the fornrcf sash-supporter represented and described, the handle of the key by heh it is operated may be of such a form as to adapt itto form a curtain-holder, the small amount of movement oi' said handle especially adapting it for that purpose. I I also propose inserting one or more springs in the window-framo ou the opposite sidefrom the supporter, furthe purpose of stea'dying` and contring the sash, when desired. l

4Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is- The combination of the widened point B', notchesor depressions A, pivoted bolt' or tumbler ,13, lock-bolt C, and sm'ings E E', all arranged and employed substantially as and for tho purposes set forth.
